Breathplay

I think it's safe to say that no matter which position one takes on it, breathplay is considered edgeplay.

These are stated as absolutes, even though we know perfectly well that there IS a level of force that can be applied to the kidney area safely, that restricted ciruclation is perfectly safe for a short time and that breathplay is commenly^([sic]) engaged in with no problem at all.

It even includes the consensual breathplay of faith (Juliette Lewis) and Max Peltier (Tom Sizemore) in Strange Days: Peltier's meta-sadistic crimes notwithstanding, he gave Faith only what she desired, and afterwards her eyes glittered "with sated lust" (Cameron and Cocks 1993).
